The difference between quasicrystals and crystals

1, stability: the crystal structure is very stable, and its arrangement and structural shape will not change obviously no matter how the external conditions change, while the structural stability of quasicrystals is relatively low, and its structure will change when the external conditions change.

2. Atomic arrangement: The atomic arrangement in an ideal crystal has long-range orderliness and periodicity, so that the crystal can fill the space without gaps, and its units can only be repeated and cannot be rotated. Quasicrystals have long-range ordered atomic arrangement similar to crystals, but they do not have translational symmetry, and their structures are also orderly, but their characteristics are that these units can be rotated.
